17, the agitator 16 is oscillated with respect to the basket to effect washing of the clothes; at the conclusion of the washing cycle, the basket and agitator are rotated in unison at high speed for the purpose of centrifugally extracting the wash water from the clothes and expelling the Water from the basket through the apertures 17; after this extraction, high speed rotation of the basket and agitator ceases, the basket is filled with a fresh supply of water, and the agitator is again oscillated in the basket to effect rinsing of the clothes; finally, following the rinsing cycle, the basket and agitator are once more rotated at high speed for a period of time sutliciently long to extract the rinse water and spin-dry the clothes. Y

As illustrated, the washing machine is provided with a dispenser-filter device indicated generally at 24. In the embodiment shown in the drawings, this device comprises a bottom or base member 25, a top or cap member 26 and a filter member 27.

The base member 25 and cap member 26 are cemented together at abutting portions such as those shown at 28 and 29 (Figure 3), and the filter member 27 is affixed to the base member as by means of fastening elements 30 (Figures 3 and 4). The base member 25 is in the form of a shallow pan and has a centrally disposed upstanding tubular post 31 which is in alignment with a hollow cylindrical projection 32 extending from the top surface 33 of the cap member 26. The aligned post 31 and projection 32 cooperate to constitute a continuous internal bore for receiving the upper end portion of the agitator. As seen in Figures 3 and 4, an annular gasket 35 of rubber or similar resilient material is fitted Within the extension 32 to provide frictional engagement between said agitator and the device 24. The base member 25 is also provided with pockets 36 adapted to accommodate agitator blade portions which seat themselves within said pockets. In this manner the entire dispenser device 24 is supportedrso as to be partly submerged in water which fills the washing basket, and is securely locked to the agitator to be positively driven thereby.

The filter member 27 is in the form of a dish in which the pan-like base member 25 and cap member 26 are nested. A bottom portion of the dished filter member- 27 has enlarged perforations 37 through which water can pass into the dispenser device and thence out through fine perforations 38 in the side wall of said filter member. The passage of water into and out of the dispenser device is effected by means of radial fins 39 which depend from the bottom of the base member 25 and which, during oscillatory motion of said device with the agitator, act as pump fins or blades.

The cap member 26 has a trough-like or container section 40 for powdered washing-aid (soap or detergent) and a receptacle section 42 for liquid rinsing-agent. The trough-like or container section 40, as best seen in Figures 2 and 3, opens through the top surface 33 of the cap member and discharges into a portion 43 of the panlike base member 25, said portion being defined and separated from the remaining portion 43a of said panlike member by means of upstanding ribs 44 which extend radially across said member. Radially extending scoops or vanes 45 and slots 46 are formed in the bottom of the pan-like member 25 said vanes serving to lift Water and pass it through said slots and into said portion 43 wherein mixing of water with soap or detergent takes place.

The receptacle section 42 is provided with an opening 47 which confronts and discharges into an annular compartment 48 (Figure 3) defined by the inner walls of the cap member 26 and by a ring 50 which is cemented or otherwise affixed to said cap member. The opening 47 is located in an upper portion of the receptacle 42 so that liquid rinsing-agent poured in a measured amount into said receptacle will not normally run out through said opening. Pouring of the rinsing-agent into the receptacle 42 is facilitated by providing the latter with a cover 51 which is made in the form of a funnel.

In use, the device 24 is snuggly seated over the upper part of the agitator center post. Before or during filling of the washing basket 13 with water, a measured quantity of washing-aid is placed in the troughlike or container section 40, and a measured quantity of liquid rinsingagent is poured into the receptacle 42. The basket is filled to a level where, at the start of the washing operation, water fiows into the pan-like member 25 of the device and mixes with the washing-aid in the portion 43, the mixture then passing into the basket. Back and forth oscillation of the device with the agitator causes the vanes 45 to pick up and discharge Water into the portion 43. In this manner water is effectively pumped into said portion 43 to dissolve the washing-aid.

During washing operation, the rinsing-agent is retained in the receptacle 42 but, following the washing operation, high speed rotation of the device with spinning of the basket and agitator to extract the washing water, causes the rinsing-agent to be ejected from said receptacle through the opening 47, and into the compartment 48. When high speed rotation ceases, the rinsing-agent flows into and remains within the portion 43a of the pan-like base member 25.

tor oscillates back and forth for rinsing the clothes in said tub.

Because of the enlarged perforations 37 in the bottomI of the member 27, water is constantly present within said member so that the fins 39 during oscillatory motion of the device, act as pump blades causing the water to circulate through the finer perforations 38. In this man' ner the device filters lint and other foreign matter from the circulating water.

After each use, the device can be thoroughly cleaned by removing it from the agitator and flushing it with clear water. Also, thorough cleaning of the removable container 42 is easily done because as seen in Figure 7, the cover 51 can be removed to give access to the interior of said container.

It will be noted that the cover 51 is provided with a depending lip 54 having a portion which is formed with av series of ridges 55 adapted to extend within the container 42 and to project transversely over the slot 47 in said container. This arrangement prevents liquid rinsingagent within the receptacle 42 from passing outwardly thereof as the device oscillates back and forth with the agitator. However the ridges provide a series of restricted passageways which allow the rinsing-agent to be ejected by centrifuge action during spinning of the device with the agitator and basket.

It should be noted that, as represented in Figure 3, the plane P-P of the outer wall of the receptacle 42 is substantially parallel to the axis of rotation A-A of the device and, as seen in Figure 2, said outer wall is In order to ensure that the rinsingagent will not run into the slotted portion 43 of said constructed on.. a; radius R, smallen than, the,A distance. between saidaxis, andsaid.' plane. InV this mannen during spinningl of the device, the: liquid rinsingagent within they receptacle: 42. is. forced.. by. centrifugal act-iontoward the point L on said outer wall where the slot 41is. located4 thereby insuring that virtually all of the liquid Within said receptaclewillibe;eiectedltherefrom;l

From the foregoing description, itwill be appreciated that the present invention provides an inexpensive and simplified arrangement whioh-` utilizes` the motions of a Washing machineagit-atorto-effct automatic addition offsoap: ordetergent to` wash- Water-in the washing basket, to'eifect.l automatic addition of'4 rinsing agent tothe rinse water filling said-y basket, andl to elf'ectf removal off lint from the water in the machine d'uring its washingfand rinsing operations'. Alsobecauserthe device of this invention incorporates means which during, agitation operates; to effect circulation of` water' from' the'. basket through said device and back to the basket, there' isproa duced a churning acti-on which cooperates with the agitator action to enhance the turning of the clothes in the water, thereby intensifying the washing andrinsing functions of the machine.

While a preferred embodiment has been shown and described, it is tobe understood that the invention embraces such changes and modifications as may come within the scope of the subjoined claims.
